Let be an acute angle. Use a calculator to approximate the measure of to the nearest tenth of a degree.

To determine the measure of the acute angle using a calculator, follow these steps:

1. ### Break Down the Problem

Since the problem does not specify a particular angle or specific trigonometric function, let's assume we are working with a function like sine, cosine, or tangent. If a specific value was to be used, please provide it to get a precise answer.

2. ### Relevant Concepts

For an acute angle $\theta$:

• If we know $\sin(\theta)$, $\cos(\theta)$, or $\tan(\theta)$, we can compute $\theta$ using the inverse trigonometric functions:
  • $\theta = \arcsin(x)$ for sine
  • $\theta = \arccos(x)$ for cosine
  • $\theta = \arctan(x)$ for tangent

3. ### Analysis and Detail

1. Enter the known value into the calculator depending on the trigonometric function you're using.
2. Use the appropriate inverse function to find the angle.
3. Make sure to set the calculator to degree mode (not radians) for results in degrees.

4. ### Verify and Summarize

Double-checking with a calculator ensures that the value you have calculated is accurate to the nearest tenth of a degree.

Final Answer

Since the specific trigonometric function or known value wasn’t provided, please provide that information to get the measure of the angle $\theta$ accurately.
